Get a full exhaust and leave stock mufflers...cheaper, quieter, better TQ, but slightly worse HP.
6th gens iirc only have the ecu's that learn around the piggybacks

the rest of the exhaust components are subjective to whoever owns the car.

I most certainly do.... Base run was with injen "cold air intake" and underpulley Last run with custom short ram intake, Gen3 Cattman headers, cattman catback, tuned to 12.2 with Greddy Blue

if you turn smoothness up to 5 your graph will look better, and will be easier to compare to others (SAE with 5 Smoothness is considered standard)

as you can see, I have a crappy AFR (very jaggy) and still pulled decent #'s...I would say this is partially due to 60 degree temp and huge fan in front of the engine

this is with I/H/E and test pipe...non SSIM....I think I would have gained 7hp/tq through the whole curve if I had a super flat AFR...and possibly another 20whp @ 6400 with the SSIM

Im sure your prolly trying to say this in lehymans terms because most people dont understand how things work and i dont mean to get offtopic but.. If thats the case why wouldnt you get an AFPR and raise the base fuel pressure while keeping it at least safe but on the high side that way you can take away airflow with a piggyback and get more timing yet still stay at a reasonable AFR sense pressure is higher more gas needs to be removed to stay at the same AFR. Of course this would shorten the life of your injectors but still not a bad move in my eyes. I do believe this is the whole concept of a bigger MAF housing aswell adding more airflow to be able to #1 get more air in, aswell as being able to pull more fuel via "airflow" that our ECU actually see's, thus more timing sense the ecu thinks your not at as high of a load as you technically are.

I wouldn't want to retro fit the fuel system of the A33B to return style. Cliffs: AFPR cannot be fitted very easily to the A33B. I just added Z33 injectors and actually did see an increase of about +3 - 5º in timing as a result of the injectors + 13.8 - 14.0 AFR,. (- 10-12% correction via SAFCII)

Nope, it's the sheer volume that adds value to the LRMAF, not timing/AFR/ etc.

lol its a two way street it adds volume yes which in turn gives it more airflow throughout the rev range, enough to take the piggyback settings down a percent or two automatically giving a small timing boost. Thats all i ment

The MAF actually sees LESS airflow when using a larger diameter MAF housing, so it seems as if that theory would be false.

Im not talking about what it actually sees im talking about whats going in why dont u just drop it already it doesnt matter and is not relitive to the thread anyway. *edit* btw its not a theory its knowlage.

What the sensor sees is what determines the timing. So no, you're still wrong.

This thread is essentially worthless since there are no dynos from the actual thread starter, only butt dynos, and reposts of previous dynos, so I will continue to do as I do.

alright, i know what the sensor sees tells the ECU which load cell to get timing from. What im saying is bigger maf housing lets more "unmetered" air in essentially leaning the AFR's out without changing a thing and allowing you to physically subtract more fuel from your piggyback tuning device, which gains the timing i speak of. Its along the same terms as say "hacking" a MAF on a dsm sensor it allows more air to travel through the same type of space. In our application using a larger sensor will in turn allow more airflow to be entered into the intake system while hitting the same load cell as before. Its all a circle and yes im right and know exacly what im talking about i tune cars for a living.

Letting in un metereds air = Lean, subtracting fuel via AFC = leaner, not smart Mr. Tuner.

Not a strong fan of SSIM. The lack of low end torque sucks. It basically has the same concept of the Kinetix manifold. both which show no real hp gains with stock rev limiter ftl.

I make more torque now than I did before I my IM was modded, so you must not have optimized your set-up. As I always say, you need to optimize your set-up in order to take full advantage of any mod.

If I do the SSIM mod on my car, I'll do the intake spacers at the same time, hopefully that will offset the loss of midrange torque.

thats what i plan on doing, along with changing my spark plugs as well.. might as well get everything done under there once you have that IM off!

Why go SSIM if you don't extend the rev limiter, and you get pissed about the loss of low end? Simple answer: don't.

That would be like wanting instant spool up and putting a T04R on your car...

LOL...good comparison, I like the SSIM, it actually did show some small gains up top and I can take the low end loss, I am only at a low RPM once when I race at the track...

i think a tad bit different then anyone else.. ive heard catman headers with a testpipe/ and exhaust setup like you have on a vq30 and it did sound a tad ricey and i believe that is cuz the headers are really nice n powerful but their equal length which gives it that ricey noise its not a choppy sound, i have the same exahust setup with no cats or anything but have the obx headers and their unequal length headers and it sounds so good n choppy Just my opinion..

funny how im lookin for info on the gen 3 headers and i get this thread with no dynos from the poster and a lot of yellin at each other haha. its funny but damn.. need some info. i wanna know if its worth the route of headers/tune or save for boost.

It's been 3 months, I don't think he's had it tuned, and if so, he hasn't posted about it.
